Magnesium is very useful for alloys. We use it for make medicines. Mg has a mass number of 24.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
Mg2+: [1s22s22p6]
Magnesium, ion (Mg2+)
The correct name of the ion Mg2+ is magnesium ion.
The Mg2 plus cation has 10 electrons.
This is a basic stoichiometry question. Things you need to know:1 mol = 6.022 x 10^23 atoms/particles/molecules/ionsRatio of Mg in MgCl2 : 1mol Mg2+/1 mol MgCl2Always start with what you are given:3.00 mol MgCl2 X 1mol Mg2+/1 mol MgCl2 X 6.022 x 10^23 ions Mg2+/ 1mol Mg2+=1.8066 x 10^24 ions Mg2+
An Mg2+ ion is a magnesium ion that has a charge of +2, meaning it has lost 2 electrons. The number of neutrons in an Mg2+ ion is the same as in a regular magnesium atom, which is 12 neutrons.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
Mg2+: [1s22s22p6]
The cation for MgCl2 is Mg2+.
10
The number of protons is 12, the number of electrons is 10, the number of neutrons is different for each isotope.
Magnesium, ion (Mg2+)
There are 1.20 equivalents in 0.60 mole of Mg2+, since Mg2+ has a charge of 2+.
The correct name of the ion Mg2+ is magnesium ion.
The Mg2 plus cation has 10 electrons.
Mg equals Mg2+ plus 2e-
